Helicobacter pylori infection increases following cholecystectomy.

Cholecystectomy is frequently linked with duodenogastric reflux and gastritis but its effect on Helicobacter Pylori (H pylori) infection has not been examined. In a prospective study, twenty two patients with documented cholelithiasis underwent upper gastrointestinal endoscopy and biopsy and 24hr dual channel pH monitoring prior to cholecystectomy and again at 3-6 months post-operatively. The antral biopsies were histologically assessed for H pylori and gastritis and awarded an alkaline reflux score. The number of patients with H pylori infection increased from 7 (32%) preoperatively to 15 (68%) post-cholecystectomy (p < 0.05). Cholecystectomy was also associated with an increase in the incidence of gastritis from 7 to 15 (p < 0.05). The increase in H pylori infection rate occurred in association with an increase in the percentage time gastric pH > 4 in the supine position, from 9.6 (2.2) to 22.2 (4.8) percent, (p < 0.01). The median chemical gastritis score, however, did not change significantly following surgery [8(3-11) vs 7(3-11)]. Seven patients remained symptomatic following cholecystectomy all of whom were H pylori positive and had gastritis. H pylori can survive in the alkaline environment which follows cholecystectomy and may contribute to the post-cholecystectomy syndrome.

Cholecystectomy and oesophageal reflux: a prospective evaluation.

The effect of cholecystectomy on oesophageal function was examined prospectively. Of 37 patients studied, 17 (46 per cent) were still symptomatic 3-4 months after surgery. Thirteen patients (35 per cent) had abnormal oesophageal pH profiles before cholecystectomy, increasing to 27 (73 per cent) afterwards (P < 0.002). The mean (s.e.m.) DeMeester acid reflux score increased from 15.2(2.1) to 34.2(5.2) (P < 0.001) after operation. Lower oesophageal sphincter function, as measured by the sphincter function index, was significantly reduced in the patients with abnormal pH profiles after operation (P < 0.01). Mean(s.e.m.) supine gastric alkaline shift (proportion of time at pH > 4) increased from 9.2(2.0) to 17.7(3.7) per cent (P < 0.02) and the incidence of gastritis from eight patients (22 per cent) to 23 (62 per cent) (P < 0.001). These data suggest that cholecystectomy results in gastro-oesophageal reflux that appears to be related to compromised sphincter competence.

Cholecystectomy and oesophageal pathology: is there a link?

Symptoms persist in a significant proportion of patients following cholecystectomy, some of which may have an oesophageal aetiology. The oesophagus has not previously been studied in this patient group. In this study all patients who had undergone cholecystectomy over a four year period were invited for review and symptoms were documented. Oesophageal function was examined and compared with normal controls. Patients were subdivided into symptomatic and asymptomatic subgroups and their findings compared. Symptoms were present in 53 percent of the postcholecystectomy group. The mean (sem) DeMeester acid score was higher in the post-cholecystectomy group -20.6 (3.6) than in controls -6.7 (0.9) (p = 0.01). The incidence of oesophagitis and gastritis were also increased in this group. There was a trend towards increased reflux and oesophagitis in the symptomatic compared with the asymptomatic subgroup. Other findings confined to the post-cholecystectomy group included nutcracker oesophagus in 4 and irritable bowel syndrome in 3. It is suggested that cholecystectomy may be associated with changes in oesophageal function which, in turn, may be associated with persistent symptoms.

[Abscess of the omental bursa (lesser sac)].

Subphrenic omental bursa abscess is frequently overlooked and the overall mortality is 70%. Early diagnosis and drainage improve the prognosis considerably. In cases with abdominal symptoms followed by pyrexia, possibly with signs of sepsis, and pleural effusion but with no or only slight findings on objective clinical examination, subphrenic abscess should be suspected and a scanning of the abdomen should be performed.
