Emergency subtotal/total colectomy with anastomosis for acutely obstructed carcinoma of the left colon.
PURPOSE: The operation of choice for acutely obstructed carcinoma of the left colon is controversial. The aim of the study was to evaluate the results of its management by emergency subtotal/total colectomy with immediate anastomosis without diversion. METHODS: An emergency subtotal/total colectomy was performed in 44 patients (mean age, 72.4 years). Inclusion criteria were reasonable operative risk, resectable acutely obstructed carcinoma, massively distended colon of dubious viability and likely to contain ischemic lesions, signs of impending cecal perforation, and masses suggesting synchronous colonic cancers. RESULTS: Postoperative mortality was 6.8 percent. Two patients over 90 years of age died postoperatively as a result of cardiopulmonary complications. An 83-year-old female died as a result of an anastomotic dehiscence. Morbidity was 6.8 percent including one fistula which recovered without surgery. There were three synchronous colon cancers. Six months after surgery, the mean daily stool frequency was two following subtotal colectomy and three after total colectomy. CONCLUSION: Emergency subtotal colectomy achieves in one stage relief of bowel obstruction and tumor resection by encompassing a massively distended and fecal-loaded colon with ischemic lesions and serosal tears on the cecum, ensures restoration of gut contiguity via a "safe" ileocolonic anastomosis, and removes occasional lesions proximal to the index cancer. It is a safe procedure given that operative mortality rates are as low as with elective surgery.

A pilot study of factors influencing bowel function after colorectal anastomosis.
PURPOSE: This study was undertaken to assess subjective bowel function after anterior resection and to search for clinical characteristics that might affect the functional results. METHODS: A total of 70 patients answered a questionnaire concerning bowel function a median of 65 months after anterior resection, and 40 patients responded to the same questionnaire a median of 60 months after colonic resection. RESULTS: Median frequency of bowel movement per 24 hours was two (range, 0.2-9) after rectal resection and one (range, 0.4-6) after colonic resection (P < 0.001). Incontinence for loose stools (P < 0.01), need to wear a pad (P < 0.05), and need to return to the toilet after defecation (P < 0.05) was more common in the rectal resection group. In the latter group, advanced age, use of descending or transverse colon for anastomosis, and large amount of intraoperative bleeding was associated with fecal incontinence (P < 0.05). Preoperative radiotherapy was correlated with a high bowel frequency (P = 0.003). CONCLUSIONS: These data indicate that alterations of subjective bowel function frequently observed after colorectal anastomosis may be affected by both surgical technique and adjuvant radiotherapy.

Coloplasty in low colorectal anastomosis: manometric and functional comparison with straight and colonic J-pouch anastomosis.
PURPOSE: After resection of the distal rectum with a straight reanastomosis, poor bowel function can occur. This is felt to be because of the loss of the rectal reservoir. To overcome this, a neoreservoir using a colonic J-pouch has been advocated in low colorectal and coloanal anastomosis. However, difficulties in reach, inability to fit the pouch into a narrow pelvis, and postoperative evacuation problems can make the colonic J-pouch problematic. Coloplasty is a new technique that may overcome the poor bowel function seen in the straight anastomosis and the problems of the colonic J-pouch. The purpose of this study was to compare the functional results after a low colorectal anastomosis among patients receiving a coloplasty, colonic J-pouch, or straight anastomosis. METHODS: Twenty patients underwent construction of a coloplasty with a low colorectal anastomosis. Postoperative manometry and functional outcome of these patients was compared with a matched group of 16 patients who had a colonic J-pouch and low colorectal anastomosis and 17 patients who had a straight low colorectal anastomosis. RESULTS: Maximum tolerated volume was significantly favorable in the coloplasty (mean, 116.9 ml) and colonic J-pouch group (mean, 150 ml) vs. the straight anastomosis group (mean, 83.3; P < 0.05) The compliance was also significantly favorable for the coloplasty (mean, 4.9 ml/mmHg) and the colonic J-pouch group (mean, 6.1 ml/mmHg) vs. the straight anastomosis group (mean, 3.2 ml/mmHg; P < 0.05) The coloplasty (mean, 2.6; range, 1-5) and colonic J-pouch (mean, 3.1; range, 2-6) had significantly fewer bowel movements per day than the straight anastomosis group (mean, 4.5; range, 1-8; P < 0.05). Similar complication rates were noted in the three groups. CONCLUSIONS: Patients with a coloplasty and low colorectal anastomosis seem to have similar functional outcome along with similar pouch compliance compared with patients with colonic J-pouch and low colorectal anastomosis. However, the coloplasty may provide an alternative method to the colonic J-pouch for a neorectal reservoir construction when reach or a narrow pelvis prohibits its formation. Technically it also may be easier to construct.

Stapler-facilitated rectal eversion.
Sphincter-preserving procedures have come to play an increasingly important role in colon and rectal surgery. In certain situations, rectal eversion can be an invaluable aid in performing a sphincter-saving operation. We present a new method to evert the rectum using the curved circular stapler.

Obstructive Ileus caused by blood clot after emergency total gastrectomy in a patient with hemophilia A: report of a case.
We report herein the extremely unusual case of a patient with hemophilia A who developed a hematoma ileus soon after undergoing an emergency total gastrectomy. Postoperatively, the patient was found to have an obstruction in the small intestine that was difficult to differentiate from intussusception. Reoperation revealed the cause of the obstruction to be a large blood clot. This case report serves to demonstrate that careful hemostasis and observation during surgery is essential in patients with hemophilia.

Development of an ulcer in the side-to-side anastomosis of a jejunal pouch after proximal gastrectomy reconstructed by jejunal interposition: report of a case.
We present herein the first reported case of a deep ulceration developing in the pouch of a jejunal side-to-side anastomosis following the interposition of a jejunal U-shaped pouch (jejunal pouch), performed as reconstruction. A 47-year-old woman underwent a proximal gastrectomy and interposition of a jejunal pouch for early gastric cancer, 4 months after which she began to develop a fever. Esophagogastroscopy revealed a deep ulceration in the side-to-side anastomosis of the jejunal pouch. Her serum gastrin level was much higher than the normal range, and 24-h monitoring of the intraremnant stomach pH revealed that it was below 7.0 at night. A peptic ulcer was thought to be one of the causes of the pouchitis. Due to the drug-resistant ulceration and fever, a reoperation was performed, in which the jejunal pouch and remnant stomach were removed and Roux-en-Y reconstruction was done. There were no postoperative complications, and the fever resolved after surgery. Reconstruction of the jejunal pouch after proximal gastrectomy is recommended from the standpoint of quality of life (QOL); however, further studies on the size of the remnant stomach and the length of the interposed jejunal pouch are necessary.

Gastrointestinal recovery and outcome after laparoscopy-assisted versus conventional open distal gastrectomy for early gastric cancer.
Laparoscopy-assisted gastrectomy has been increasingly reported as the treatment of choice for early gastric cancer. However, there is little information regarding the benefits of laparoscopy-assisted distal gastrectomy (LADG). LADG and conventional open distal gastrectomy (DG) for early gastric cancer were compared in terms of operative outcome, recovery of bowel function, complications, and changes in body weight. Thirty-four patients underwent LADG for early gastric cancer. These patients were compared with 31 patients who underwent DG during the same period. For estimating gastrointestinal motility recovery, 20 radiopaque markers were inserted into the duodenum during surgery, and abdominal X-rays were taken daily until all markers were seen in the ascending colon. Age, gender, and histologic differentiation of the lesions were matched. The LADG group required a significantly longer operative time and the dissection of fewer lymph nodes. Postoperative hospital stay and the occurrence of postoperative complications (ileus) were significantly shorter and less frequent in the LADG group. The LADG group showed a more rapid recovery of gastrointestinal motor function compared with the DG group during the early postoperative period. Body weight 24 months after LADG was about 100% of pre-illness weight, but no further weight change was encountered in the DG group. For selected patients with early gastric cancer, LADG with lymphadenectomy can provide a rapid recovery and good quality of life without compromising the cure rate.

Laparoscopic pancreatic surgery for islet cell tumors of the pancreas.
The experience with laparoscopic pancreatic surgery (LPS) in general, and pancreatic islet cell tumors (ICTs) in particular, is still limited. Because insulinoma is the most prevalent tumor and is mostly benign, single, and curable with surgical excision, it comprises most of the cases. Our experience with 17 cases (10 insulinomas, 2 gastrinomas, 1 nesidioblastoma, 4 nonfunctioning tumors) and those recorded in the literature (93 cases) show that laparoscopic surgery for small, solitary benign islet cell tumors located in the body and tail is feasible and safe and can result in rapid postoperative recuperation and a complication rate comparable or lower than that achieved with open surgery. It duplicates the success rate seen with conventional surgery regarding intraoperative localization and cure of disease. The main morbidity continues to be the occurrence of a fistula (18%), most often after enucleation, but the clinical course is benign in most instances. Preoperative imaging studies are required for localization, and the combined use of biphasic helical computed tomography and endoscopic ultrasonography (US) seems to be cost-effective. The use of laparoscopic US is an integral part of the laparoscopic procedure, and the information achieved is valuable for both confirming localization and decision making concerning the most appropriate surgical procedure. In cases of distal pancreatectomy, splenic salvage, preferably with preservation of splenic vessels, is feasible albeit more demanding and can be achieved in most cases.

Transabdominal modified devascularization procedure with or without esophageal stapler transection--an operation adequate for effective control of a variceal bleed. Is esophageal stapler transection necessary?
BACKGROUND: In Japan, the original Sugiura procedure reported favorable results in non-cirrhotic patients but in the West, the modified Sugiura procedure is not widely accepted because of high rebleeding, morbidity, and mortality in cirrhotics. We retrospectively analyzed the efficacy of our modified Sugiura procedure i.e., devascularization with/without esophageal transection combined with salvage endotherapy and pharmacotherapy for control of a variceal bleed. MATERIALS AND METHODS: Between January 1999 and December 2004, 912 patients with variceal bleeding were treated. Of these, 66 (7.2%) patients were subjected to surgery after failed endotherapy/propranolol. Among these 66 patients, 52 had transabdominal devascularization (16 emergency, 36 elective); 14 patients underwent devascularization with esophageal stapler transection (group I), and 38 patients had devascularization without esophageal stapler transection (group II). Another 14 patients underwent elective end-to-side proximal splenorenal shunt surgery. RESULTS: Postoperative mortality was 7.1% in group I, 10.5% in group II (P>0.05). Mortality for emergency surgery was 31.2% (5/16) but there were no deaths in the elective surgery group. Overall morbidity was 57.1% in group I and 21.0% in group II (P<0.05). The rates of variceal rebleeding were 7.1% and 7.8%; residual varices were 30.7% and 32.3%; recurrent varices were 7.6% and 5.8% following the group I and group II procedures, respectively, over a mean follow-up period of 39.9 (7-2) months. Esophageal transection-related morbidity (leak, stricture, and bleeding) was 21.4% (3/14) in group I. CONCLUSIONS: Devascularization without esophageal stapler transection is a safe and effective procedure for adequate (urgent and long-term) control of variceal bleeding with similar results and less morbidity when compared to devascularization with esophageal transection in cirrhotic patients, as well as non-cirrhotic patients.

Results of the Mutaf procedure in patients with gastroesophageal reflux disease.
Operations to treat complicated gastroesophageal reflux disease (GERD) have become the third most commonly performed general surgical procedure in large pediatric centers, and many surgical techniques have come into use to prevent gastroesophageal reflux. This paper presents our experience with gastric tube cardioplasty, a new procedure described by Oktay Mutaf (Mutaf procedure). Eleven children with GERD were successfully operated on. The postoperative period was uneventful, and all patients were symptom-free.

The clipped intestinal non-perforating anastomosis of small bowel: a new technique.
In contrast to adult surgery, the neonatal small intestine confronts the surgeon, depending on the age of the patient, with variable diameters of the intestine. Therefore, anastomoses are usually performed by hand with interrupted sutures. In the presented study, a new technique is demonstrated. An anastomosis in the distal ileum of Sprague Dawley rats was performed with a single clamp applicator (Anastoclip). Small bowel anastomoses were performed in 32 rats. The clipped bowel anastomosis was evaluated concerning stenosis, leakage, and adhesions in comparison to the sutured anastomosis. Tension test and X-ray examination were performed to measure the stability. The rats were sacrificed at day 3 or 14 after laparotomy. The clipped anastomosis is feasible, and faster to perform than the conventional hand-sutured anastomosis (Operation time: control group: 18.5 min versus clipped group 4 min; p > 0.05). Furthermore, there were differences in the mechanical stability, with higher tension forces needed for rupturing the clipped anastomosis. There were fewer stenoses (16.5 mm stenotic diameter in the control group versus 20.6 mm in the clipped group) and fewer adhesions in the group of the clipped anastomosis. Histological examinations were performed and did not show significant differences between the two groups. In the animal model presented, the clipped, intestinal, non-perforating anastomosis (CINPA) shows advantages compared to the common hand-sutured anastomosis.

Principal modifications of the Duhamel procedure in the treatment of Hirschsprung's disease. Analysis based on results of an international retrospective study of 2,430 patients.
In the literature, many articles refer to the DUHAMEL technique or some of its modifications in the treatment of Hirschsprung's disease, however, no complete review of all of them has been published to date. The authors present an analysis of the principal modifications of this technique based on the results of an international retrospective survey that evaluated a series of 2,430 patients as well as data from the literature. The important role of the internal anal sphincter in the physiology of continence is emphasized; understanding its function is an imperative prerequisite for a successful Duhamel procedure. The original technique, which used two crushing Kocher clamps as proposed by Duhamel in 1956, as well as a majority of the modifications with various spur-crushing instruments are no longer in use. At present, surgeons generally use staplers for the colorectal anastomosis.

Comparison of early and 1-year follow-up results of conventional hemorrhoidectomy and hemorrhoid artery ligation: a randomized study.
BACKGROUND AND AIMS: Doppler-guided hemorrhoid artery ligation is a new approach for treating hemorrhoids. Early and 1-year follow-up results of the procedure are presented and compared with those of closed scissors hemorrhoidectomy in a prospective randomized study. PATIENTS AND METHODS: Sixty consecutively recruited patients were randomized into two groups: group A ( n=30) was treated with standardized closed scissors hemorrhoidectomy and group B ( n=30) with Doppler-guided hemorrhoid artery ligation. The follow-up period was 11.7+/-4.6 months. RESULTS: The average need for minor analgesics was 11.7+/-12.6 doses in group A and 2.9+/-7.7 in group B. Patients in group A spent 62.9+/-29.0 hours in hospital postoperatively and those in group B 19.8+/-41.8 hours. Return to normal daily activities took 24.9+/-24.5 days in group A and 3.0+/-5.5 days in group B. Neither the disappearance (26 vs. 25 patients) nor the recurrence of preoperative symptoms (5 vs. 6 patients) differed significantly between the two groups. CONCLUSION: Both procedures were effective in treating hemorrhoids. The 1-year results of Doppler-guided hemorrhoid artery ligation do not differ from those of closed scissors hemorrhoidectomy. Doppler-guided hemorrhoid artery ligation seems to be ideal for 1-day surgery, and it fulfills the requirements of minimally invasive surgery.

The endoscopic stapler diverticulotomy for Zenker's diverticulum.
This paper describes the surgical procedure of the endoscopic stapler treatment of Zenker's diverticulum and analyzes the results of 24 consecutive operated patients. In three patients the endoscopic exposure of the diverticulum was not possible. Twenty-one patients underwent endoscopic stapler treatment without any peri- or postoperative complications. The follow-up period was 4 to 29 months (average 18 months). The average total time for surgery was 25 min. Postoperatively, a nasogastric feeding tube was not necessary: all patients resumed oral intake 12 h after surgery. Discharge from the hospital followed the 2nd postoperative day. All patients had complete or nearly complete resolution of symptoms at the 4-month follow-up. Recurrent complaints were an indication for repeat of the contrast barium esophagram. Two patients revealed a residual diverticulum 7 and 11 months after treatment. In comparison with results and complication rates in the literature of the external, transcutaneous techniques and endoscopic diverticulotomy procedures, the endoscopic stapler treatment of Zenker's diverticulum is a safe, (cost-)effective and minimally invasive method and to be considered as the initial treatment of choice.

Tensile strength of mesh fixation methods in laparoscopic incisional hernia repair.
BACKGROUND: Fixation of the mesh is crucial for the successful laparoscopic repair of incisional hernias. In the present experimental study, we used a pig model to compare the tensile strengths of mesh fixation with helical titanium coils (tackers) and transabdominal wall sutures. METHODS: Thirty-six full-thickness specimens (5 x 7 cm) of the anterior abdominal wall of nine pig cadavers were randomized for fixation of a polypropylene mesh (7 x 7 cm) by either tackers or transabdominal wall sutures. The number of fixation points varied from one to five per 7-cm tissue length, with distances between fixation points of 2.3, 1.8, 1.4, and 1.2 cm, respectively. The force required to disrupt the mesh fixation (tensile strength) was measured by a dynamometer. Statistical analysis was performed using the Wilcoxon test and the Spearman rank correlation test. RESULTS: The mean tensile strength of mesh fixation by transabdominal sutures was significantly greater than that by tackers for each number of fixation points: 67 N vs 28 N for a single fixation point (p <0.001), 115 N vs 42 N for two fixation points (p <0.001), 150 N vs 63 N for three fixation points (p <0.05), 151 N vs 73 N for four fixation points (p <0.05), and 150 N vs 82 N for five fixation points (p <0.05). Increasing the number of fixation points over three per 7 cm (distance between fixation points of 1.8 cm) did not improve tensile strength. CONCLUSION: The tensile strength of transabdominal sutures is up to 2.5 times greater than the tensile strength of tackers. Therefore, the use of transabdominal sutures for mesh fixation appears to be preferable for laparoscopic incisional hernia repair.

Tailored approach to Zenker's diverticula.
BACKGROUND: Zenker's diverticula (ZD) can be treated by diverticulostomy or open surgery (upper esophageal sphincter myotomy and diverticulectomy or diverticulopexy). The aim of this study was to compare the outcome of the two alternative treatments. METHODS: Fifty eight patients were scored for symptoms and upper esophageal sphincter (UES) pressure; relaxations and intrabolus pressures were recorded by manometry. Treatment depended on operative risk and ZD size. Twenty four patients with high surgical risk and/or a <3-cm or >5-cm pouch underwent diverticulostomy; the other 34 had open surgery. RESULTS: Mortality was nil. Five patients had postoperative complications after open surgery (p<0.05). Hospital stay was shorter after diverticulostomy (p<0.001). Follow-up (41 months; range, 1-101) was obtained in 53 patients. Postoperative manometry showed a UES pressure reduction, improved UES relaxation, and lower intrabolus pressure in both groups (p<0.05). In the diverticulostomy group, three patients complained of severe dysphagia. vs none in the open surgery group (p<0.05). CONCLUSION: Diverticulostomy is safe, quick, and effective for most patients with medium-sized ZD, but open surgery offers better long-term results and should be recommended for younger, healthy patients with small or very large diverticula.
