Choledochoduodenostomy in the management of common duct stones or associated pathology--an obsolete method?

UNLABELLED: Choledochoduodenostomy (CDD) has been reported as a more effective treatment of CBD stones than T-tube drainage but it is regarded as a last resort or obsolete therapeutic method due to fears of higher mobidity, cholangitis, "sump" syndrome and liver dysfunction. We aimed to assess the aforementioned issues analyzing prospectively our experience from 1976 through Dec.92. METHODS: CDD was performed in 89 females and 36 males, aged 60 +/- 8.7 years, 26 during repeat surgery. Duct stones were the indication in 94, Sphincter of oddi (SO) dysfunction in 23 and obstructive pancreatitis nodule in 8. Peroperative liver biopsies were obtained in 44 patients. The "follow-up" schedule (> 2.5 years in 110) included clinical interview and LFT's on an yearly basis. Ultra sound (USG) was obtained every one or two years. ERC was done in 10 symptomatic patients and in 25 others for protocul purposes. Liver biopsies were taken four to nine years post surgery in 11 patients-five at relaparotomy for non-biliary causes and six percutaneously by fine needle. Ductal mucosa biopsy could safely be performed in one patient 10 years after surgery. The long-term results were classified as excellent, good, fair or poor. Poor meant the need for further invasive therapy (resurgery or EST). RESULTS: There were two operative deaths (1.6%). The long-term results (123 survivors) were considered excellent in 89, good in 22, fair in 9 and poor in three. Three patients died from unrelated causes and eight others ceased the "follow-up" evaluation three to five years post surgery. All of them were considered as having excellent or good results. A widely patient anastomosis of approximately 20 mms without mucosal inflammatory changes was documented in every patient assessed via ERC. food "debris" was detected within the distal duct of four patients yet it was easily flushed through the stoma. Normal tissue patterns were observed in all long-term liver biopsies. Likewise the ductal mucosa biopsy failed to reveal any acute or chronic inflammatory changes. CONCLUSIONS: 1) CDD is a highly effective short and long-term treatment of CBD lithiasis.2) It does not lead to bacterial or "chemical" cholangitis, to "sump" syndrome or to hepatic dysfunction, provided a wide anastomosis is accomplished.3) CDD should only be considered as obsolete after extensive, long-term, prospective, randomized assessment of laparoscopic or combined laparoendoscopic approaches have been shown to be as effective as or superior to CDD.

Standard surgical approaches to primary choledocholithiasis--definitive versus temporary decompression.

The occurrence of retained/recurrent calculi after primary CBDE followed by temporary T-tube decompression, have remained at rates varying from 5.4% to 20.9% over the last 10 years in spite of sophisticated pre and intraoperative imaging techniques. It is postulated that a functional obstruction, due to dysmotility of the SO, lies behind most stone-containing ducts. Thus it seems logical to us that a permanent "fenestration" should be the management of most such ducts. We prospectively followed-up, for one to 10 years, two groups of patients submitted to primary CBDE aiming to assess the short and long-term results of two different surgical approaches to duct lithiasis. In one (Group A) 162 CBDE's were performed, out of 680 CHE's (24%), with a "positivity" of 68% and in the other (Group B) 80 CBDE's, out of 438 CHE's (18%), with a "positivity" of 70%. In Group A a T-tube decompression was used in 79(49%) and a definitive drainage in 83(51%) whereas in Group B the T-tube was employed in only 3(4%) and some form of permanent "fenestration" in 77(96%). There were no significant differences between the operative mortality rates, which were 2.5% in Group A (1 death post T-tube, 3 post CDJ) and 1.3% in Group B (1 death post CDD). The long-term results, though, were significantly worse among patients of Group A whose ducts were temporarily decompressed: 10/79 (12.7%) required further aggressive interventional therapy for retained/recurrent stones while only 3.8% (3/80) in Group A and 1.3% (1/76) in Group B required revisional surgery for bilio-digestive anastomotic complications with cholangitis. It is concluded that it is against the long-term efficiency of the approach utilized in Group B that the new laparoscopic techniques should be compared.

Side-to-side choledochoduodenostomy in the management of choledocholithiasis and associated disease. Facts and fiction.

Ascending cholangitis, the sump syndrome, and alkaline reflux gastritis are drawbacks commonly ascribed to side-to-side choledochoduodenostomy. Most surgeons consider side-to-side choledochoduodenostomy as a last resort measure to be utilized only in elderly patients and only on ducts wider than 15 mm. In trying to assess the pertinence of such alleged inconveniences and limitations, a series has been analyzed (retrospectively until 1976 and prospectively from then on). A total of 70 of these operations were performed from January 1973 to September 1982, on 53 women and 17 men. Twenty-six percent were less than 50 years of age, and 30 percent were over 70 years of age. Sixteen of the 70 operations were reoperations that took place several years after cholecystectomy. Intravenous cholangiographic films were obtained preoperatively for evaluation of the duct width which was less than 15 mm in 23 patients (33 percent). The follow-up period, surpassing 2 years in 35 patients (50 percent), includes clinical interviews and liver biochemistry measurements every 6 months, and endoscopic retrograde cholangiopancreatography 12 to 18 months postoperatively. There was one postoperative death (1.4 percent), and significant morbidity developed in five patients (7.1 percent). The postoperative hospital stay averaged 8 days. The long-term results were classified as excellent in 50 patients, good in 15 patients, fair in 3 patients, and poor in 1 patient. Side-to-side choledochoduodenostomy is a safe, very effective therapeutic measure, even when performed on ducts less than 15 mm wide, provided a few technical requirements are respected. It does not carry the inconveniences that have usually been ascribed to it. The excellent long-term results in the present series have allowed us to liberalize its utilization, especially in young patients.

Total gastrectomy for cancer: is reconstruction or a gastric replacement reservoir essential?

Malnutrition is a frequently observed complication of total gastrectomy. Does the mode of reconstructing the alimentary tract bear part of the responsibility? We assessed our experience from January 1975 to 1992 to analyze this issue. A series of 64 total gastrectomy patients [40 men, 24 women; aged 59 +/- 11 (SD) years] were considered. Preoperative and periodic follow-up evaluations were prospectively documented: upper gastrointestinal series, endoscopic examination, complete blood count, serum and liver biochemistry profiles, serum proteins, tranferrin, serum iron and calcium, iron-binding capacity, oral glucose tolerance test, ultrasonography or computed tomography, actual and ideal body weight and performance (AJCC/UICC) assessments. Symptoms were classified by means of Cuschieri's scoring system. Esophageal mucosal changes (edema, hyperemia, erosions, ulcerations) were documented on endoscopy. There were 36 of 58 operative survivors who had no evidence of tumor recurrence and were available for long-term evaluation (12-132 months). An RY loop had been constructed in 25 patients, 5 with a Hunt pouch; 9 had an isoperistaltic jejunal interposition (IJI), 4 with a Kock pouch; and 2 had a Braun loop. A 60 to 70 cm long jejunal limb was always utilized. Statistical analyses were obtained by means of the Student t-test and the equality of medians test. Progressive malnutrition was observed in patients with the Braun (omega) loops, both patients displaying persistent esophagitis and dietary restrictions. Both recovered ideal body weight after remedial surgery that transformed the omega loop into an RY loop. Both RY and IJI loops effectively prevented alkaline esophagitis.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term clinical and endoscopic assessment after total gastrectomy for cancer.

Progressive malnutrition has been reported as a long-term consequence of total gastrectomy (TG), possibly related to the mode of reconstructing the intestine. In reviewing our personal experience (1975-Sept. 91), we attempted to correlate the reconstructive technique used with the subsequent course of the patient. A consecutive series of 62 TGs (59 adenocarcinomas, 3 lymphomas) in 38 males and 24 females 59 +/- 11 (m Mean +/- SD) years old was reviewed. Preoperative and "follow-up" evaluations, including upper gastrointestinal series and/or endoscopic examination, complete blood count, serum and liver biochemistry profiles, serum iron and plasma transferrin, oral GTT, USG or CT scan, actual and ideal body weight (IBW Life Extension Institute of New York), and "performance status" assessments, were prospectively documented. The follow-up symptoms were classified as per Cuschieri's scoring system. The endoscopic esophageal mucosa assessments were documented as well. Among 56 patients surviving operation, 34 were available, without tumor recurrence, for long-term (12-132 months) evaluation. A Roux-en-Y loop reconstruction had been performed in 23, 5 with a Hunt-Lawrence pouch; an isoperistaltic, esophagoduodenal, jejunal interposition (IR) was performed in 9, 4 with a Kock pouch; and an omega loop reconstruction was performed in 2. A 60-70-cm-long jejunal limb was always utilized.(ABSTRACT TRUNCATED AT 250 WORDS)

[Surgical management of acute, malignant obstruction of the left colon with colostomy].

One-stage subtotal colectomy of an acutely obstructed left colon would improve quality of life while shortening the length of hospitalization. Prohibitive mortality rates, however, are ascribed to such an approach. Analyzing the Senior Author's experience we compared the one-stage approach versus the multi-stage resections concerning operative mortality and morbidity rates and the duration of hospitalization. Forty-nine of 291 (17%) large bowel cancers presented acute left-sided obstruction requiring emergency surgery. Colostomy alone was performed in 18 (37%), multi-stage colectomy in 20 (41%, Group A) and one-stage subtotal colectomy in 11 (22%, Group B, all of them after 1979), the years under scrutiny being from 1973 through Sept. 1990. Both groups were comparable in age and sex distribution, TNM staging and ASA classification. Operative mortality and morbidity rates were 10% and 30% in Group A, 9% and 18% in Group B, respectively. The average length of hospitalization was 21.25 days (14-30) in Group A, 9.18 days (7-14) in Group B. Whenever an experienced surgical team is available and in the absence of contra-indications (local factors precluding a swift dissection, hemodynamic instability, gangrenous bowel) a one-stage subtotal colectomy, taking advantage of a better healing ileo-sigmoid or ileo-rectal anastomosis, carries acceptable mortality and morbidity rates while enhancing the quality of life and shortening the length of hospitalization. It should be considered the choice procedure, provided selection requirements and technical demands are met. An evaluation of the Senior Author's team experience (1973-90) in the management of acutely obstructing left colon cancer (49/291 or 17%) provides information on multi-stage resections and one-stage subtotal colectomy (Group A and B) as regards operative mortality (10% in Group A, 9% in Group B) as well as length of hospitalization (21 days in Group A, 9 days in Group B).(ABSTRACT TRUNCATED AT 250 WORDS)
