From November 1970 to August 1974 small intestinal bypass was performed in 475 patients for morbid obesity with an operative mortality of 1.6%. Immediate postoperative complications were superficial wound infection (17 patients), pulmonary complications (seven patients), cardiac complications (five patients), wound dehiscence (nine patients), intestinal tract fistula (four patients), and miscellaneous complications (14 patients). Delayed complications included hypokalemia (28%), hypocalcemia (9%), anemia (11%), calcium oxalate urinary calculi (6%), gout (2%), and hepatic failure (1.4%). Fourteen patients died of late complications. Ventral incisional hernia occurred in 3% of the patients; failure to lose sufficient weight in 21%, all but one occurring in patients with end-to-side shunts. Thirteen end-to-side shunts have been converted to end-to-end shunts because of insufficient weight loss. A team concept is important in the handling of the morbidly obese. Small bowel bypass is effective in producing sustained weight reduction in these patients. Careful and continued study of these patients for the rest of their lives is of paramount importance.

At the University of Minnesota under the supervision of one staff surgeon both jejunoileal bypass (JIB) and gastric bypass (GIB) operations have been performed for weight reduction in morbidly obese individuals. During the last 14 years 727 patients underwent end-to-end (40 to 4 cm) JIB and more than 570 patients underwent GIB. This report is based on a comparison of 205 JIBs performed between July 1975 and July 1979, 106 Alden-loop type GIBs (GIB-loop) performed between July 1975 and July 1979, 53 loop GIBs with enteroenterostomies between the limbs of the loop (GIB-EE) performed between May 1980 and May 1981, and 57 Roux-en-Y GIBs (GIB-Roux) performed between May 1981 and May 1982. Adequate weight loss occurred in 80% of the patients who returned for follow-up in all groups. The percentage of excess body weight loss was similar for the first year (65% for JIB, 62% for GIB-loop, 69% for GIB-EE, and 71% for GIB-Roux). The operative mortality and the immediate morbidity rates were uniformly low. The long-term complications for JIB were 37.7% arthralgia, 7.1% oxalate urolithiasis, 5.6% incisional hernia, and 1.4% liver failure. The complications for GIB-loop were 10.2% nausea/vomiting, 1.9% bile reflux gastritis, and 2.8% anastomotic problems; for GIB-EE 23% nausea/vomiting, 7% bile gastritis, 4.6% incisional hernia, and 3.7% anastomotic problems; and for GIB-Roux 16% nausea/vomiting and 1.7% anastomotic problems. The anastomotic problems consisted of afferent loop obstructions and stomal stenosis; there were no leaks. At 1 year plasma cholesterol reduction for JIB averaged 42% (p less than 0.001), GIB-loop 14% (p less than 0.001), GIB-EE 7% (NS), and GIB-Roux 17% (p less than 0.001). One year after operation 49% of 88 JIB patients showed progression of liver disease on sequential biopsy specimens and 20% improvement. In the 78 GIB patients with sequential biopsies, liver disease progressed in 8% and improved in 65%. In summary, comparable therapeutic weight reduction occurred with all the assessed procedures; however, the GIB-Roux was associated with far fewer serious long-term complications. At this time the GIB-Roux procedure is the weight reduction operation we recommend.

At the University of Minnesota, under the supervision of one staff surgeon, both the jejunoileal bypass (JIB) and gastric bypass (GIB) operations have been done for weight reduction in morbidly obese individuals. Over the past 11 years, end-to-end (40 to 4 cm) JIB performed for 727 patients. In addition, antecolic GIB was performed for 364 patients over the past 6 years. This report is based primarily on a comparison of 205 JIB and 106 GIB patients with surgery between July 1975 and July 1979. Adequate weight loss was seen in 75% of each group. The percentage of excess body weight loss was similar for the first year (65% for JIB and 62% for GIB); however, the JIB patients started at 214% of ideal weight and GIB patients at 197% of ideal weight. The operative mortality rate for either operation was well below 1%, and the immediate operative morbidity rate was low and only rarely delayed discharge from the hospital. The long-term complications for JIB were 37.7% arthralgia or arthritis, 7.1% oxalate urolithiasis, 5.6 incisional hernia, and 1.4% liver failure; complications of GIB were 10.2% nausea and/or vomiting, 1.9% reflux esophagitis, and 2.8% anastomotic problems. At 1 year, plasma cholesterol reductions for JIB patients averaged 42% (P less than 0.001), whereas for the GIB patients it ws only 14% (P less than 0.001). At 1 year after operation, 49% of 88 JIB patients showed progression of liver disease on sequential biopsies, with 31% unchanged and 20% improved. In 43 GIB patients, the biopsies showed improvement in 58%, an unchanged status in 30%, and worsening in 12%. The levels of serum glutamic oxaloacetic transaminase and alkaline phosphatase increased after JIB and eventually returned to normal, while GIB patients had only minor fluctuations of liver function tests. Comparable therapeutic weight results occurred with JIB and GIB; however, the GIB was associated with far fewer serious long-term complications and the JIB with a far greater cholesterol lowering. A percentage of the GIB patients showed progression of liver disease at 1 year after bypass.
